Does the resurfacing implant remove more bone from the pelvis than a standard total hip replacement?
Because the head is significantly larger than that of the standard total hip replacement, one might think that more bone would need to be removed on the pelvis side, but this is generally not true. The outside diameter of the acetabular component is similar in size to the typical modular total hip replacemet acetabular cup. This is because the resurfacing implant has a single part acetabular cup, the two-part nature of the shell-and-drop-in-liner style modular component ads to the thickness of the THR component. If this is a concern in your case, you should verify the outside diameters of the components that you are considering.
